The Earth's Systems!

The four spheres of the Earth are:

• Biosphere - The word Bio is Greek word for life; it relates to the living things.
• Geosphere - The Geosphere is like the skull of the earth; it is the non-living things.
• Atmosphere - Is the surrounding of the earth; relates to air.
• Hydrosphere - Links to water and all its other forms, ice, sea, lakes and rivers.

Definition:

The four spheres (Geosphere, Biosphere, Hydrosphere and Atmosphere)
work together to create ecosystems.

Ecosystems are:

A combination of the four spheres in one place/working together.

This picture is a ecosystem because it has a mixture of the four spheres. The biosphere (Trees, grass, plants), geosphere (rocks, mountains nonliving things), the hydrosphere (the pond and the water in the clouds) and the atmosphere (the sky, clouds, the air).
